lMPROVEMENTlN MACHINES FORQCLEANIQNG CARPETS.

Specification forming part of Letters Patent No.17 1,727, dated January4, 1876; application filed November 4, 1875.

To all whom it may concern.-

Be it known that 1, JAMES HOTHERSALL, of

New York, in the State of New York, have cess for the purpose ofcleaning the same;-

and, further, in the arrangement of a cord on each side of the machine,directly behind the double beaters, running backward and forward betweenthe frame of the machine, having one of its ends fastened to the frame,and the other end to a tightening-spindle, thus forming an open andelastic back'for the action of the heaters. v

In the accompanying drawing, Figure I represents a front view of myimproved machine embodying my invention. Fig. II is a cross section ofthe same, and Fig. III is an end View, showing the gearing.

Similar letters represent similar parts in all the figures.

To the frame of the machine bars B B B B are arranged, as well ascarrying-rollers O and D. The carpet, shown at A, Fig. II, which isfastened together on its two ends, so as to form an endless hand, ispassed over those bars B B B B, and between the rollers O and and D,receiving by the action of said rollers a regular motion around themachine. On the side of these rollers the brush-roller E is arranged,below which the carpet is made to pass. On each side of the machine,between the bars B and B,'a cord F is stretched, attached at one end tothe frame of the machine,

and then passed backward and forward from one end to the other, overpulleys a, to prevent the wear. and tear of the cord, and fastened atits other end to a spindle, n, provided with a ratchet-wheel and pawlfor the purpose of tightening said cord, and to hold the same in thedesired tension. In the front of the I cords F, and in the spacehetweenthe bars B- B, two or more rows of beaters, G, are arranged,turning in suitable hearings in the frame of the machine. These heatersare placed close to each other, and their arms are so arranged that thearms of one beater pass between the arms of the next beater, and theheaters in the lower row are placed between those of the upper rows insuch a manner that the arms of the heaters in this lower row will actagainst that part of the carpet not acted upon by the arms of theheaters in the upper row. Against the front and back-of the machine barsJ are arranged, guided through the rods L L in the end of themachine-frame, and by suitable rollers m. These bars J are arranged withsuitable jaws or openings'to allow the ends of the shafts H to passthrough, and are provided with frictionrollers 0;, against which cams-K, fast on the ends of the shafts H, are made to act to communicate areciprocating motion to said bars 'J. Rods N connect these bars J withthe arms to attached to the heaters G, and communicate thereby thedesired motion to said heaters G. The shafts H H are provided withsuitable gearing M M, operated by wheel av fast on the driving-shaft P.On this drivingshaft P a pulley, (1, com mnnicates motion through theband Q to the shaft R, provided with a pinion, 0, operating the wheel Son the end of the brush-roller E, as well as the wheel T on the end ofthe carrying-roller D. Upon the other end of the roller Da pinion, V, isarranged, meshing into a pinion, W, fast to the roller 0, and. thuscommunicates the desired motion to the same.

The bars B B have a bottom plate, Y, fitted between them and the ends ofthe machine to collect the dust beaten out of the carpet, which may bearranged to draw out of one side of the machine for the purpose ofemptying the same. The carpet being placed around the bars B B B B,between the rollers O and D, passing under the brush-roller E, andhaving its ends connected together, forming thus an endless band, asrepresented in Fig. II, is then in position to be operated upon. Motionbeing given to the shaft P the several parts will be operated in themanner above de- I scribed. The rollers O and D will gradually e andregularly draw the carpet around the inachine, ijwhich will; thenbe'brushed while passingnnder the brush-roller E, while that part ofthecarpet hanging straight at the front a and back of the machine, betweenthe bars B B, will be acted upon by the arms of the a y heaters G. i

The gearing Operating these beaters G is so arranged that the heaters inthe upper row will act alternately with the heaters in the lower. row.The cord F, stretched from s one end of the machine to the other end,between thebars B and B, backward and forward, will form. an elasticback for the carpet a when acted upon bythe heaters, yielding a slightlyat its upper or lower part whenever a the upper orlower heaters act uponthe carpet,and, forming thus a perfectly open back, willallow the dustto pass throughand fall upon the bottontplate Y.

WhatI claim as my invention, and desire tosecure by Letters Patent, is-

1 The bars B B, carrying-rollers (J and D,

brush-roller E, and cords F, in combination with double heaters Gr,arranged in relation, with the cordsF onqboth sidesofthe machine,

and operating upon a. carpet connected to gether at its ends,substantially as herein described. a s

2. The cords F stretched between the bars B and B, having one endfastened to the frame, and the other end to a spindle, a, provided witha ratchet-wheeland pawl, in combination with rollers a,in*then1anner andfor the purpose substantially as specified. a

3. The combination of cams K, attached to the end of shafts H, bars J,provided with friction-rollers o, rods N, arms 10, and heaters G,substantially as described and set forth. 1

4. The position of the heaters G, alternately to each other in the upperand lower rows, to

act upon different parts of theycarpet, in the manner and for thepurpose substantiallyas specified.
